Best place in metro Boston to let your fog run free. Tons of space and lots of great trails once your best friend us done playing in the fields with all the other furry companions

A dog-heavenly as it gets...plenty of room to run and play with other dogs , huge open fields , trails , and lakes , beautiful scenery and fresh air

Great hike trail for walk. Lots of dogs & families. Beautiful reservoir view .

Great park just outside Cambridge for hiking and biking , bring your dog!

Awesome hiking spot. Quick and easy to get to from the city !

great little trails and a safe place to let your pup run off-leash.

Come for the off leash dog park , stay forever waiting for a parking spot .

If you're bringing a dog, be careful when taking him or her off the leash. There have been a few coyote sightings recently

Love to go to fells reservation best palce to bring ur dog@@

Dogs are allowed off leash here...some dogs owners are good but others not so much....and there is dog poop everywhere...it is quite unfortunate that this beautiful place had been trashed.

Excellent place to unleash your dog to play with other dogs !
